I cannot use the bash script you uploaded.
To make this a valid ticket, please provide one (or more if necessary) FFmpeg command line including the complete, uncut console output here in the ticket, do not use external resources.

that is a drag'n'drop batch (not bash) which resides in the same ffmpeg.exe folder,
cutted cli for first and second files (2 pass each)

ffmpeg.exe -y -i Fallout4.mkv -c:v libvpx -pass 1 -b:v .5M -threads 7 -speed 4 -colorspace "bt709" -auto-alt-ref 1 -lag-in-frames 25 -an -f null NUL
ffmpeg.exe -y -i Fallout4.mkv -c:v libvpx -pass 2 -b:v .5M -threads 7 -speed 2 -colorspace "bt709" -auto-alt-ref 1 -lag-in-frames 25 -f webm test_0.5_vp8.webm
ffmpeg.exe -y -i Fallout4.mkv -c:v libvpx -pass 1 -b:v 1M -threads 7 -speed 4 -colorspace "bt709" -auto-alt-ref 1 -lag-in-frames 25 -an -f null NUL
ffmpeg.exe -y -i Fallout4.mkv -c:v libvpx -pass 2 -b:v 1M -threads 7 -speed 2 -colorspace "bt709" -auto-alt-ref 1 -lag-in-frames 25 -f webm test_1.0_vp8.webm

this is a cut of the console output for first and second files

using x264, vp9 works, as with other sources too

I re-checked x265 and it works too

Do you know how this version string can be produced? I get N-81489-ga37e6dd here.

Do you only get broken output for test_1.0_vp8.webm if you encode another file before?

I compiled it with media-autobuild_suite

nope sometimes even the first file, as I notice using a single pass compression don't returns a broken output. but I'm not sure is a ffmpeg's fault or a libvpx's one.
test files which give broken results are both 1920x1080 bgra ffv1 mkv.
If you need files I can upload them.

I don't know why there was so much duplicates

Your description indicates a hardware error (of possibly an error in libvpx) afaict.
If you disagree, please test vanilla (unpatched) FFmpeg before reopening this ticket.

I tested it with Zeranoe's lastest x64 build (version N-81664-g6f062eb) on my pc and on my father's one, and I get bit-identical files with the same artifacts.
I also tested piping from ffmpeg to vpxenc.exe (the same compiled with media-autobuild_suite, so same libvpx as the non vanilla I used) with:

"ffmpeg.exe" -i test17.mkv -pix_fmt yuv420p -f rawvideo - | "vpxenc.exe" -t 8 --fpf="test2.log" -w 1920 -h 1080 --i420 --fps=60/1 --codec=vp8 --cpu-used=2 --good --end-usage=vbr --target-bitrate=500 --passes=2 --pass=1 --auto-alt-ref=1 --lag-in-frames=25 -o NUL -
"ffmpeg.exe" -i test17.mkv -pix_fmt yuv420p -f rawvideo - | "vpxenc.exe" -t 8 --fpf="test2.log" -w 1920 -h 1080 --i420 --fps=60/1 --codec=vp8 --cpu-used=2 --good --end-usage=vbr --target-bitrate=500 --passes=2 --pass=2 --auto-alt-ref=1 --lag-in-frames=25 -o test2.webm -

as you can see I omitted

 --color-space="bt709"

coz vp8 doesn't have a --color-space parameter

The file looks ok.

Above you wrote that you get artefacts "sometimes" and after running several encodes, now they are identical in runs on different hardware.
If you can always reproduce the issue, please provide one (!) command line together with the complete, uncut condone output and one input sample that allows to reproduce the issue.

Component: undetermined → avcodec
Reproduced by developer: set
Summary: Corrupted like VP8 video → vp8: auto-alt-ref does not work with transparency

Patch sent, work-around is to force -pix_fmt yuv420p.

Yep I wasn't getting this kind of artifacts on the first run (is a batch of encodes at many bitrates), but after even on it (maybe coz I was testing with a 1 minute file and I cutted them to 2s?), but only with those brga files, not with yuv files nor using libx264 libx265 or libvpx-vp9.

I was no sure if it was an ffmpeg, an y4m decoder or a libvpx-vp8 bug.

I can confirm, without -lag-in-frames 1 or with -pix_fmt yuv420p the result file is OK.

Should be "fixed" in 44bcb636c1a7052059330c3edbd900246e15ae60, thank you for the report!
